The Environmental Protection Agency (EPA) is proposing amendments to its Underground Injection Control (UIC) program regulations (40 CFR parts 144 and 146) as they pertain to Class II (oil and gas-related) wells. The proposed amendments revise current provisions relating to construction standards and apply the "area of review" and corrective action requirements to previously exempt wells "authorized by rule."

The proposed modifications build upon recommendations made by a Federally-chartered Advisory Committee pursuant to the findings of an internal Mid-Course Evaluation effort and a General Accounting Office Report.

Under the provisions of Section 1425 of the Safe Drinking Water Act (SDWA), these amended regulations would not need to be adopted verbatim by the States; however, EPA will require that "primacy" States demonstrate that their programs are still effective in light of these new Federal requirements.
